[WORKED FOR ME ON STOCK KK WITH STOCK RECOVERY]
This guide will prepare you well to battle against all the Fake/Refurbished LG G3's present in the Market.
I recently upgraded to LG G3 D855 and was faced with alarming numbers of Refurbs.
In this guide, i'll explain each and every step that I produced to avoid any refurbished or Fake G3
Q.What the heck is 'Refurbished'?
Well, you already know its basic meaning but i'll ponder upon the Refurbished G3 D855.
Refurbished G3's typically show D855 in the 'About Screen' and even you can put the Hidden Menu Code i.e 3845#*855#. Almost all assume that its an ORIGINAL/GENUINE D855. In most cases, that's not true lad :crying:. All D855 Refurbs got D850/VS985/LS990 mobo and thus you will not be able to mess with it or even install a Custom ROM on it. Above all, it's a Fake one Dude! That's not what you paid for.
Now if you follow each and every step carefully, even if you are a noob, you'll eventually end up with a Genuine D855 :good:
Things you need BEFORE buying..
1. Laptop/PC
2. Attached adb files within this thread.
3. Data Cable.
Instructions:
1. Enable Android Debugging by hoping into Developers Options.
2.Go to Setting->General->About->Software Info->Build Number [Write it down as you'll need this Later!]
3.Change the Connection mode to MTP.
4.After extracting the attached folder, Right Click on it WHILE holding the Shift key. Now click on "Open command Window here" and type the following commands.
adb devices
[Now you'll see an Authentication Box on your device, check trust this computer and hit OK]
Now Type,
adb reboot recovery
Here comes the moment of truth
At top of the recovery screen you'll either see D850/VS985/LS990 or your Build Number. It's quite obvious that if your Build Number appears, you got a Genuine D855. If you get some other crap written there then all my apologies with you mate!
PS: I didn't include the IMEI check as all these Refurb phones come with Original D855 IMEI. Never Trust the IMEI check under no circumstances!
Troubleshooting:
Q.'Device Not found' Error after following the set of adb commands?
Make sure after typing 'adb devices' you get the 'Android USB Debugging' Dialog on your device, else you can try reconnecting the cable or even using another port on your Laptop/PC.
Q.My Phone booted into TWRP/CWM?
Well, that happened with a friend of mine and now it's quite tricky to check if it's a D855 or any other. You can try making a backup of EFS (or any other partiton) and reboot your device after that. Now browse into TWRP folder and hop into Backups folder. If you see a LGD850xxxxx (or anything like LGVS985xxxx etc) then it's a refurb set else if you see LGD855xxxxx, you can calm down now as it's a D855.
Good Luck, Hit 'Thanks' if this saved your a**[emoji14]
I got mine refurbished, but it's genuine! Thanks for the guide, saved my butt, haha!

No it doesn't.
I saw my build number, but why did I get the service disabled after Lollipop update
Cz it only works with Stock KK with Stock Recovery.

Try restarting device or your pc
So, basically, you just entered recovery mode, yes? Can't we just use hardware button combinations (power vol down) to enter recovery mode instead? Does it had any differences?
I am planning to buy a second-hand G3 and I need a LOT of fake checks to test...

Technically, Yes! You just gotta enter Recovery Mode. I didn't check if Hardware Buttons work or not on Stock KK Recovery.
Can you post the Results? I'll update the guide then.

Exactly, Hardware Button combo would let to a Factory reset. The only solution is to access Recovery via adb.
LG G3 D855. Can't upgrade KK to MM
Hi,
I recently bought a "LG G3 D855 32GB 4G LTE Unlocked" from amazon which came with Android KK. Everything looked genuine. But for the life of me, I just couldn't upgrade to MM neither with LGUP or LG Flash Tool. I checked everything. TWICE ! Made sure I had the right USB drivers, run the tools as Administrator, redownloaded the kdz file a number of times. Nothing. So I suspected it might be either fake or refurbished. I tried what was suggested here and I couldn't get to what I was expecting to be the recovery mode. The phone just factory resets and boots up, or if I use adb shell as advised it just reboots. What am I missing ?
Thanks.

You can get Lollipop OTA upgrade to make sure you have got the genuine version if the lollipop OTA works on your device.
and
Also have you downloaded the correct drivers, have proper USB cable and booted phone into download mode to apply KDZ update. If it still don't work then give a try to tot method.

Well the procedure i produced worked on various genuine/fake G3's. Hardware Button combo would definitely let to a factory reset so *The Only* way to access Recovery is via adb shell and make sure you type the whole command i.e "adb reboot recovery"

For now, I have sent the phone back to amazon. Hopefully I'll be getting a replacement in a few days. I'll try again and report back here. Can you confirm if i don't have to root the phone and install a custom recovery tool before running "adb reboot recovery" ?
Thanks,
I'm confused
I was under the impression that refurbished phones were the exact same thing except they have to go through more checks after they have been fixed. What am I missing?

if you manage to install the driver the rest should go easy.
It's weird, on some systems it wont install the driver properly(adb) but google nexus driver installs fine.

Ultra brick G2 vs980! T_T
Good night lords of XDA!
I come to you after exhausting all that I could find and try, hope you can enlighten me, you would save a new G2 that is about to become a gleaming brick:
Summary: I have in hand a Verizon LG G2 vs980, with the intention of using it in Spain. After a bad flash a ROM for a different model, you could not access recovery mode or download mode, only fastboot.
Thanks to this great tutorial, I could flash by ADB and fastboot files an official ROM for this G2, but after a correct process, the G2 restarted and only shows "Security error" before shutting ...
I still do not have access to recovery or download, and now not to fastboot. Only allows me to access the screen "Factory reset", but in doing nothing changes.
How could re-flash a recovery or something like that allows me relive my G2?
Thank you very much in advance. You are my salvation. XD
PS: I apologize for any clerical error or misused term. I do not usually write in English.

Sorry, wrong thread. XDD
I recently got my hands on a bricked LG G2 D800 because i thought i was deemed unbrickable. I got the device the backlight showed life and that was about it. i managed to somehow get (this method i think) it to boot to the LG logo and than it jumps to fastboot mode.
Yea me!!! I got fastboot and this phone is as good as fixed. NO! fastboot does not work. It will absolutely not execute a command besides "fastboot devices" to which it brings up a fastboot device. Since i got fastboot my plan is to follow this thread to recover the device. i updated all drivers that i need for this device, nothing. Plain and simple, there is an issue getting fastboot to execute command. the commands appear on the device but it doesn't advance further.
Download mode. Yeah i get the download mode that I get is a "security error" so its not the traditional download mode. if i get download mode i can flash a .tot right? Wrong. Fails due to "model information check". i got the phone to appear under COM41. The .tot file is 'LGD800AT-01-V20c-310-410-FEB-02-2014+0.tot'. Drivers does not seem to be the issue at hand, unless maybe its the ADB/fastboot drivers which i also updated to newest version.
The next thing im contemplating if this method is worth the shot. I have it booting to fastboot. I will probably do this since its probably the only thing left to try. Going to set up linux now so i'll report back.
Any help/insight will be appeared and properly thanked for.
I also got security errors on an 802. I was about to leave the phone in download mode and ran the LG Mobile Support Tool to perform an upgrade recovery to get a stock LP ROM onto the phone.

I just downloaded the LG Mobile tool from LG Canada. Just search for the d802 and download the program. The program should detect your phone and download the correct firmware.

I actually have the d802 and it worked with the LG mobile program from the Canadian website.

I was trying to install a custom recovery (twrp) by several different methods, with absolutely no luck (but that's another secondary issue at this point) and i screwed something up. Not exactly sure but i think the last thing I did was:
using "Rashr - Flash Tool" i think i went to "flash kernel from storage" then flashed boot.img.
now the phone goes immediately, directly into fastboot even without being connected to computer.
so i tried getting into the stock recovery by holding "volume down" and "power" until lg logo, releasing the reholding until factory reset screen. after choosing yes 2 times i get a
"boot certicification verify" or something message for about a second then it goes to this screen (sorry but apparently i haven't had enough posts on the forums to include clickable links.)

ok, i do have access to fastboot (actually, as soon as i power it on, it immediately is in foastboot mode, even without being connected to computer). i tried using srktool's repair tools via fastboot. it seems like it's working (ie phone shows that it receives command) but that's it. does it take a loooooong time or something?
btw, i can also get into download mode by holding "vol up" while plugging into computer. so, i tried using srktool utilites via download mode and nothing.
also, i just noticed that while connected to computer in download mode, in device manager it shows G2 under "portable devices" with an exclamation point on it.

not sure what you mean by "lg mobile support tool". i googled it and found and installed "lg pc suite". is that the same thing?
nevermind that last question. i found and installed and tried the upgrade recovery tool but for some reason the phone wont go into download mode anymore. when i power it up whith ""vol +" help down, it shows download mode for a second, but then goes right into fastboot mode.
Is it recognized by the program in fastboot mode?
Here's the program I was referring to: http://www.lg.com/ca_en/support-mobile/lg-LGD803
Even though the program says it is for the 803, I used it to recover my international d802.

flash stock ROM via download mode or flash custom ROM via twrp.
the first choice (stock ROM) is better
thanks for the responses!!
before i saw your reply, i flashed the stock .tot firmware and now i have my phone back.
but, before all this started, it was lollipop(5.0.2) and now it's Jellybean(4.2.2). i bought phone on ebay, so im assuming that it got lollipop via an ota update. so now i'm looking into flashing it back to lollipop. what's the easiest method to install stock lollipop?
Hello XDA
As title say, I 'm going share my experience in this thread.
History
I purchased this device almost 8 month back.Purchased from a local store.Was very smooth and i was satisfied with the performance.Battery was good.Got regular update and these updates are from google,so why not install it,right?Then this Android N came,and i was so happy.7.0.0 was good.Then the nightmare 7.1.2 came.Phone started to lag continuously,Battery drained too much.But I was like Okay.May be this will fixed in new update.Then suddenly one day my phone was stuck.Not booting.Stucked at Google.I understood that phone already booted and fingerprint was too working but it showed nothing on display just black light.I was afraid as i didn't purchase it from Google Play or any authorized seller.So no warranty or chance of having replacement.So I started searching about this issue and found not only me many people are facing this.But there are no proper guideline or solving this issue.Tried everything and ended up with Locked Bootloader Irony!
Journey
As i never try to mess with my phone because it was Nexus 5x! So i never touch OEM or try to unlock the bootloader.So i tried to access stock recovery,But Alas! in recovery Volume up and down wasn't working.So I couldn't wipe or factory reset.So Now ended up with :
1.Locked Bootloader
2.Locked OEM
3.Recovery Stuck
Googled and found many solutions but none of them came to solve my issue.So i thought why not flash stock rom.But HOW! Cause fastboot only work with unlocked bootloader.And you can't unlock bootloader when your OEM is locked and you can't unlock it with fastboot.It can be only unlocked from developer option only.GOD!
Now I have only 2 options left:
1.Fastboot mod where no functions working
2.Download Mod (This will save you)
Now fastboot option is out and only download mod option is available.So what can i do with Download Mod?
LGUP TOOL helped me.Downloaded a tot file for Global version (LGH791) and flashed it and stucked at google logo and in recovery too.But next time i flashed the same file in a different way.Ok here it is:
1.Drivers are important here.I'm using windows 10.I have adb and fastboot and Lg drivers.Workplace okay.
2.Opened device manager and change the com port of Android phone 3 to 41. Port Changed!
3.Connected my phone to pc using 3rd party cable (Careful here,try to use original cable.) and entered into download mod and.
4.Opened LGUP Tool ,checked REFURBISHED mod,checked BIN file and select the tot file downloaded before.And quicky close it.(No need to click start)
5.Then again opened lg tool and click start.(BIN Checked and it showed the previously selected tot file).No need add anything new this time,just open and click START.
6.Rebooted and again stucked at Google screen.But wait! recovery is working.Pressing and holding volume up button for a while then a android logo with red cross inside will come up.Now holding power button and volume down button at the same time,Recovery will show and menu is working.Great!
7.Now Wiped cache and factory reset.And after that selected Apply update from Adb sideload
8.My device was connected to pc from the beginning,right? Now i downloaded a file previously called bullhead-ota-opp2.170420.019-c449d2bb.zip from Google Nexus 5x OTA update page.
9.In Adb folder,copied the file and named it ota.zip.Opened a command prompt using shift+right click in the folder.Phone was on Adb sideload mode.Typing this command adb sideload ota.zip
10.This took more than 8-9 minutes to finish.After flashing and phone rebooted.WOW
11.Couldn't believe my eyes.The OTA update was about Android O.I quickly enabled the developer menu and made oem unlcocked and usb debugging on.Boot into bootloader and unlock bootloader with this command fastboot flashing unlock
12.Now bootloader is unlocked and i flashed TWRP recovery for future need.
13.Rebooted the phone and after using for 1 minute the phone freezed again
14.This is the end of the story for today.
Planning
I'm thinking the OTA update was the problem.Now I'm downloading 6.0.1 version.And will do a clean install.Let's see what happens next.
Any kind of help is appreciated.If you think there is something i'm missing here then please suggest.
And Thanks to XDA.I got all these helps from here.Will update the post tomorrow.
You downloaded Android O Developer Preview. Final OTAs are here:
https://developers.google.com/android/ota
Just try flashing newest Factory Image via fastboot, but don't forget to flash TWRP back:
https://developers.google.com/android/images
TBH I NEVER thought this phone will be dead by hardware failure all of a sudden, I dont mind another few hundreds bucks but the problem now is the fking data within it.
Cant even pass google logo if you choose Recovery Mode
GG LG, well played
I have a 16gb variant dead....same issue like urs .....can i use the same lgh791 tot file?... in fastboot it says lgh791 16gb
usefully

I STRONGLY recommend that the original post is corrected to change "Download mod" to "Download mode" in all of its four occurences.
Same for one ocurrence of "Fastboot mod".
It is horribly confusing as it is, as calling them "mod" implies some modification you have to apply to the phone (be it software or hardware).
same of my expirience, flash 4CoreOreo..
my nexus 5x now is fully working

I suppose that makes sense. Then again, when an instruction is telling you to boot into download mod.....using common sense I'm gonna understand that's a typo and they meant download mode. But you're right, for some folks that may be a bit of a challenge. Common sense isn't as common as it was when I was young.
And the links?
I'm brazilian and i'm having a hard time to find the links to download stuff. Mine is dead and bootloader blocked. The tutorial seems to work but i can't understand well
Interesting. Thanks
I was trying to update with LGUP application for firmware update but didn't success, so I removed the USB cable and pressed Volume down and power button to restart. But it went straight into Firmware Update and LGUP application can't find the port.
So, my phone is stucking in Firmware update screen, please help me how to restore the firmware and get out from Firmware Update screen, many thanks and greatly appreciated.
Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.
Enter download mode and connect the phone in the PC. Download LG brige and open it. When you are inside the programe you will see a window of Software update enter here and there is an option that is for bad installation otas (to reinstall and correct errors). Use this and I think this will handle.
Another option I think is using LG Up you will see your device in download mode. Try to enter download mode and see if this works also.
Thanks both - I ran into a similar situation. I pulled down both the 11a and 14a KDZ files, and used UpperCut and LGUP to flash first the 14a and then the 11a image. Unfortunately in both cases after LGUP does its thing, I'm getting the LG logo, followed by fastboot screen.
I cannot reboot to get past it, and I cannot flash recovery (it says the boot loader is locked). I cannot flash the Unlock.bin from LG because apparently the KDZ re-enabled the software lock prohibiting bootloader unlocks.
So I'm suck with a phone that will only boot into fastboot, stock recovery or into download mode, and I cannot figure out how to get back to something functional. I've tried reflashing with LGUP - that doesn't work. And the LG Bridge "Update Error Recovery" option gives an error "Connect your mobile device to the USB Port" even though it is, and the LG USB drivers are installed.
Would appreciate any pointers someone could offer.

In older LG phones work LG Flashtool (2014)...Maybe with this you can flash KDZ firmware https://forum.xda-developers.com/showthread.php?t=2797190

I have the same issue - I was on Lineage os and flashing the OTA update caused bootloop to recovery. So I wanted to flash back to stock using LGUP and 14A. I did that before without issues.
This time though all installed fine but after reboot the phone immediately goes to fastboot, exactly as described above. I just spend several hours trying to fix it but with no results. The LG Bridge won't recognize the phone no matter what I do in Windows (tried 3 different PCs). On a Mac it will start connecting and will end up saying "you need to enable MTP connection".
From what I garther the stock rom flashed fine - the factory reset works, even shows "erasing data", the LG UP recognizes the phone as 14A (I tried 11A, 13A too - seems to install fine but goes immediately to fastboot after reboot).
The only thing I realized I did different when flashing the stock rom with LGUP was not using the original LG USB cable. But reflashing with original cable makes not difference now - still going to fastboot.
Any help would be greatly appreciated.
Have you guys been able to do the Upgrade recovery in the LG support tool? Did it work? It starts fine for me but after downloading the recovery file I always get and error, see the screenshot.
I was able to grab the kdz file and tried to flash it with LGUP but still the same thing. It seems like it flashes fine but after reboot it immediately goes to fastboot

Sadly I'm in the same boat as well. I'll pull some of their error messages I've gotten with LG Flash Tool this afternoon. I've tried 2014 and 2017. Both to no success.
I suspect it may be something with the /misc partition. Im going out on a limb, but I'm guessing that the AOSP and Lineage ROMs may touch misc. That partition may have some key identifiers for the LG tools. And the KDZ doesn't have a misc partition embedded inside it.
I was hoping the kdz file I was able to grab from the Lg Support tool would be different from regular stock rom 14a that is available around the internet but it appears to be exactly the same file (based on the file size). My original hope was that the file would support "Refurbish" option in the LGUP tool but it only works with "Upgrade".
I wonder if the "Refurbish" option would fix this and re-flashed all partitions - if only we could find a kdz file that would work with the refurbish option. So far all files I tried (11a, 13a, 14a) only support the upgrade option.
Thanks for all of your helps, I used LGUP and WondersMobile application on the computer and LGUP can not see the port. I did un-install the WondersMobile and LGUP can see the port and finally upgraded to latest firmware.

I too am having same problem. I've tried all the images from 11A to 14A, all of them flash with no errors on LGUP and every time LGUP detects the phone as having the last version flashed. Unfortunately, the phone also boots to fastboot every time. Nothing else to add to your descriptions at this time I'm afraid...

I am absolutely positive my problem is at least in part due to a messed up /misc partition though. @gqo actually described what I did pretty thoroughly in his thread, albeit in a G5. Post #9 has the fix but it didn't work for me.
I've also stumbled upon a menu under the Firmware Update screen that I had never seen before and cannot fin any mention to... Would any of you guys know what it is for? It reads something like:
Code:
** SELECT MENU **
** Select : Power Key(Long) **
** Move : Power Key(Short) **
-> MA-USB(WIFI) DL
POWER OFF
PHONE INFO
BACK
Okay, I figured it out. The menu, at least the first option, appears to be for Wi-Fi firmware update. I wonder what file the phone actually downloads... And if it would be able to fix our phones. The only unprotected network I had in hand was a mobile hotspot in my not-so-LTE Nexus 5, so I got as far the firmware download start but didn't risk it on such a slow and unpredictable network. On top of that my Nexus 5 has also gotten pretty good at bootlooping, that's why I got this G6 in the first place. If anyone out there has a reliable unprotected network and nerves of steel it could be interesting to see if the outcome of this update is different from the LGUP one.
How do you access this menu?
What I started working on yesterday is trying to build a image file for the Qualcomm Flash Image loader and see if I can flash the phone using this tool... But I have never used this tool before, right now it does not detect my phone - I need to work on that + see if I can correctly build the image file from kdz. I found some youtube step by step tutorials so we will see. I will post update on the progress tonight or tomorrow.

I'm not sure if there's a better way to do it, but I access it by removing the usb cable after I successfully get in Download Mode. Then I'm not sure if there's any specific key combo, I've been randomly pressing the power and the volume down buttons and at some point I get into that menu. In the menu though, for some reason, I think I can only select an option if I long press both the volume down and power buttons. The "POWER OFF" option has come in handy because so far is the only way I can actually turn my phone off. The "PHONE INFO" hasn't worked for me yet. The menu also reacts when you add/remove the microsd card... I wonder if it can be used for something other than a WiFi firmware upgrade. I haven't had the chance to connect the phone to a computer to see how the device is recognized, if at all.
And that image you're working on sounds like a neat idea, I wish I could help but I'm afraid I wouldn't have the skill. I may be able to test though. Anyway, Godspeed!

I'll play around a bit and see if I can land on this menu. At this point I'll try anything. I'm on an iPhone until I get this fixed - so I'm motivated!
I can setup an open guest network off my main wi-fi this evening and see what I can find out.
EDIT Sorry, I tried playing around here, but I couldn't figure out how to get back into the the menu you uncovered. If you could give some instructions on how to do it, I'm happy to give it a shot on my device.
I was able to access the menu today...what worked for me was at the firmware screen unplug the usb cable and then press volume down and power button three times quickly. I tried to connect to a wifi and it does not really do anything. I think it just establishes wifi connection but it does not download anything on it's own - it's waiting for another connection.
Also I got stuck with building the image file from kdz, it has no information on partitions. At this point I decided to ship to LG for a quote and will see how much they will ask for a reflash.
I got as far as selecting a network and getting some sort of a download start screen, but I interrupted it right away so I wasn't sure the download would actually go through... Apparently it does not. If this menu has some sort of flashing capabilities though, it might be worth checking how secure it is. If someone can get it to download and flash a modded file perhaps there could be a chance of flashing a custom recovery or something... I'm thinking about those guys that have an unlockable bootloader (which we ironically also have now).
Anyway, all of this goes well beyond my skill so I followed your example and submitted a repair service request to LG. It'll take quite long but shipping is free, so I figured I'd give it a try. I'm assuming this is an easy fix with the right software tools, so I hope LG doesn't overcharge for it. I'm even half hoping they'll do it under the limited warranty... If I recall correctly unlocking the bootloader doesn't immediately void all warranty, there's room to prove the bootloader was never actually unlocked. And after all LG does say that once unlocked, it cannot be undone and our phones are, in fact, running stock firmware and have a locked bootloader.
Update: My phone was received today by LG. In LG's Track Repair page, the status briefly showed as Undergoing Diagnostic but quickly moved to Repair In Progress, it's current status. Given that LG was supposed to contact me in case the repair was not covered by the limited warranty, meaning that an extra fee would've to be paid, I'm assuming the phone will be fixed (if possible, that is) free of charge. I will update you guys again soon, but if anyone out there is still struggling with this issue I'd recommend considering sending the phone to LG.
I have the exact same problem. Please keep us in the loop of what happens to your phone with LG
My phone has been received by LG for this issue on 9/26. It quickly moved through diagnostic to "repair in progress" on the first day plus showed ETA back to me in 6 business days. Ever since that it's stuck in that mode, no update or contact from LG. I check the status every day - every day it says the same - ETA 6 business days. It's been a week and half now with no update. I kind of expected it's going to take 2-3 weeks but annoyed that they say 6 days ETA and then you don't hear from anyone for almost 2 weeks with no change in status.
Update #2: The status finally moved to Shipped To Customer. I haven't been contacted by LG yet, so I guess the phone could've been shipped fixed as much as it could've been shipped as is for being unfixable. Either way, I wasn't and most likely won't be charged. FedEx hasn't got an ETA for the delivery, but I'll let you guys know as soon as I get my phone back.
Edit: Got an e-mail from LG. It reads something like:
Defect: Software failure
Payment Type: NOT APPLICABLE
Repair Results: S/W upgrade (download)
Repair Cost: $ 0.00
Warranty Status: In Warranty
Tax: $ 0.00
Total: $ 0.00
I guess I got away with it, I hope you guys do too.
